摘　　要：达朗贝尔方程及对应推迟势是研究电磁辐射的理论基础,求解推迟势是教学的重点.而在电动力学大多数教材中利用达朗贝尔方程求推迟势时采用先猜想后验证的方法,笔者阐述了在此内容教学用到的直接法,并对比两方法探讨电动力学课堂教学.D ＇Alembert equations and corresponding retarded potentials are the basic theory to study electromagnetic radiation. To solve the retarded potential is the focus of teaching. In most of electrodynamics textbooks , the method of verification after first guess is adopted to obtain the solution of D ＇Alembert equations, in this paper, we teached the content by the direct method , and compared two methods to investigate the teaching method of electrodynamics.

关 键 词：达朗贝尔方程 推迟势 直接法
